COMPUTING-SCALE.

SPECIFICATION forming part of Letters Patent No. 576,468, dated February 2, 1897.

Application filed December 18, 1895. Serial No. 572,560. (No model.)

Ie it known that I, ORANGE O. OZIAS, of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Computing-Scales; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specilication, and to the lettersof reference marked thereon.

This invention relates to improvements in that class of scales in which a balance-weight or sliding poise is employed, with an indicator to register with a graduated scale to indicate the cost of articles placed on the platform or receiver, such graduated scale usually being movable and havinga series of sets of graduations thereon computed at different rates per unit; and it is the object of the invention to enlarge the capacity of such scales, whereby the cost or value of an article may be read instantly when its weight is greater than can be counterbalanced by the sliding poise, thereby necessitating1 the use of some one of a series of removable counterpoises or weights of different size.

The invention consists in a novel arrangement of the graduated indicating scale or scales for determining the cost price of articles balanced by any one of a number of removable counterpoises and also for determining the cost price of articles balanced bythe sliding poise, all as will be hereinafter more fully explained, and pointed out in the appended claims.

The accompanying drawing illustrates in front elevation a pair of scales embodying my invention, a portion of the inclosing casing of the cylinder upon which the sets of indications are marked being broken away to illus- It will, however, be obvious to those skilled inthe art that any desired forml of scales may be employed, and the value indications or computations may be indicated on any surface or body in position for the indicator to register therewith, and hence the form of scale shown and a cylinder with the indications marked thereon is employed only as a matter of preference and convenience in illustrating the invention.

The scales proper need no description further than to say that A is the platform, and B the beam upon which the sliding poise O slides. This sliding poise itself constitutes the indicator for registering with the sets of indications or cost graduations on the cylinder, for which purpose it may have a pointer or linger, such as c. On the end of the beam there is the usual pendantB for removable counterpoise-weights.

The cylinder D is shown as coniined within a housing or casing E and supported on the base, although it may be on the beam or other moving part of the scale, as in other scales of this general class.

The surface of the cylinder D is divided by a series of sets of graduations into spaces indicating fractional parts and multiples of the prices per unit. In the illustration the rate at the opening is fifteen cents per pound, as shown by the figures at the extreme right, and the major vindications in said set are marked 10, 20, 30, and so on up to 140, these gures being the cost price of articles balanced by the sliding poise when the indicator registers therewith. The number of minor or fractional graduated spaces varies with the rate price, being wider in the set for lower unit prices and narrower for the higher unit prices, all as in other computing tables heretofore made.

In order now to enable removable supplemental weights to be employed and the cost price of articles balanced thereby, with or without the sliding poise, to be read at a glance, I form on the surface of the cylinder or table a supplemental set of distinctive gradu# ations, preferably extending entirely across the table or rate graduations. These supplemental graduations in the illustration are marked on the casing from l to 10, inclusive,and the supplemental or removable counterpoise-weights are preferably numbered to correspond to these graduation-m arks. These supplemental or distinctive graduations and the rate per unit graduations are so proportioned to each other that the cost of articles balanced by any one of the supplemental or removable counterpoise-weights will beshown by the figures on the rate per unit graduations at the point where the supplemental graduation numbered for that weight intersects the said rate per unit graduations when IOO said ligures are multiplied by ten or a cipher added thereto. For example, it' an article weighing sufficient to balance the next to the lightest, or No. 2O weight, is placed on the platform an inspection ot the distinctive graduation, Ne shows the ligure 30, and this multiplied by ten, or a cipher added, gives $3.00." Should the article have been slightly heavier than this and the sliding poise have been brought into use to secure the balance, then the cost indication regisi tering with the indicator is added to the three dollars, thus, say the sliding poise had stopped at 50, the user would see at once without :further computation that the total cost was three dollars and titty cents.

For convenience the supplemental or dis tiuctive graduations are regularly spaced and indicate pounds when read in connection with the sliding poise. The scales in the example illustrated has therefore a capacity of ten pounds, and the supplemental or removable counterpoise-weights are t'or ten, twenty, thirty pounds, tbc., up to one huiulred pounds, it so desired, corresponiiling in number to the number of graduatioils and increasing the capacity ot the scale for computing up to one hundred and ten pounds.

It will be noted that each of the distinctive graduations gives the value of its supplemental or removable weight in each et the sets of price per unit graduations, this result bein g attained by forming a number et' grad uations between each two distinctive marks corresponding to the rate per unit. Thus when the rate is ten cents per pound there are ten spaces between the distinctive or supplemental graduations, and when the rate is twenty cents per pound there are twenty spaces between such graduations, dc.

In the example illustrated the prices per unit tor the tour sets oll graduations shown are live, ten, liiteen, and twenty cents per pound, and if, for instance, the fourth or forty-pound weight be added to the beam it will be seen at the point where the casing is broken away that its value in the respective scales will be two, tour, six, and eight dollars, respectively.

The invention may be applied to any ol' the 4coiuputing-tables now in use on computingscalcs, and hence I do not wish to limit my invention to the particular embodiment illusstrated or tov any particular mechanical embodiment.

Having thus described my invent-ion, what l claim as new isl.. A price-indicating scale lor computingscales, having' a series ot' sets ot graduations for indicating cost of articles balanced bythe sliding poise, and supplemental or distinctive graduations in each ot said sets, each dis tinctive graduation indicating in each ol the sets of cost graduations a decimal-fractional part of the cost of articles balanced by one el' the removable counterpoise-weightsg substantially as described.

i. A priceindieating scale lor computing scales, having a series ol' sets et' grzuluations for indicating cost of articles balanced. by the sliding poise, and a series oi' regularly-spaced supplemental or distinctive graduations extending transversely through each ot the scries of sets ol graduations and cach distinctive graduation indicating n each set a deei mal-fractional part of the cost ol. articles balanced by a removable counterpoise -wcighl corresponding to that graduation; substantially as described.

f3. In a price-scale, the combination with the platform7 beam, poise sliding on the beamv and the series of graduated scales with which the poise registers to indicate the cost at dil'- ferent rates per unit, ot' a series ol' removable counterpoise-weights and a distinctive set oi' reglilarly-spaced graduations extending transversely of all the ii rst-mentioned series oi graduated scales and each distinctive graduation indicating a decimal-fractional part ol the value of articles balanced by one ot' the removable counterpoiseweights in all ot' the scales; substantially as described.

l. In a computing-scale, the combination with the platform, beam, poise sliding on the beam and series ol removable counterpoiseweights, of the rotary member having' the se ries of sets of graduations thereon with which the sliding poise registers to indicate cost prices at dill'erent rates per unit with a sup plemeutal or distinctive set of grfuluations extending around the rotary member and intersecting the inst-mentioned sets, each distinctive graduation indicating in each scalo a decimal-fractional part o L` the value ol articles balanced by one et' the removable coun,- terpoise weights and indications showing which graduation is to be read in connection with any particular removable weight; substantially as described.
